The temperature sensor cables must be routed separately from mains voltage cables,
and must not, for example, be routed in the same cable duct!

Caution
The controller operates with Pt1000 temperature sensors which are accurate to the degree, thus ensuring
optimal control of system functions.
Caution
Position the sensor precisely in the area to be measured!
Only use immersion, pipe-mounted or fl at-mounted sensor suitable for the specifi c area
of application with the appropriate permissible temperature range.
Sensor cables for S1 and S5 can be extended to a maximum of 30m using a cable with a
cross-section of at least 0.75mm². Sensor cables for S2 to S4 and S6 can be extended to
a maximum of 10m using a cable with a cross-section of at least 0.75mm². Make sure that
there is no contact resistance!
Connect the VFS sensors with the matching jacks.
To prevent damage to the Direct Sensors it is highly recommended to install them in to
the return.
When installing the Vortex Flow Sensors (VFS), observe the correct fl ow direction!
